scope:

This part of IEC 62053 applies only to newly manufactured static watt-hour meters of accuracy classes 0,5, 1 and 2 for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. Note 1: For other general requirements, such as safety, dependability etc., see the relevant IEC 62052 or IEC 62059 standards. This International Standard applies to newly manufactured electricity metering equipment designed to: • measure and control electrical energy on electrical networks (mains) with voltage up to 1,000 V a.c, or 1,500 V d.c.; Note 2: For a.c. electricity meters, the voltage mentioned above is the line-to-neutral voltage derived from nominal voltages. See IEC 62052-31:2015 table 7. • have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays; • operate with integrated or detached indicating displays, or without an indicating display; • be installed in a specified matching sockets or racks; • provide additional functions other than those for measurement of electrical energy.
